refactor(worker): remove config file and deprecated CLI flags

Remove -c (config file), -p (remote port), -m (remote host) flags.
Worker now uses CLI defaults (localhost:9990) or --peers for HA.
No config file dependency — four settings don't justify file overhead.
Default remote_port changed from 6789 to 9990 (controller default).
